I saw this question on the main site today as I was also trying to solve the same problem. I also found that the OP asked the same question on another website, which was answered there.
This also solved my problem and I was wondering if this answer could somehow be documented on SO. Of course, it would be better if the OP documents the question by answering it, linking it, and giving credit to the original answerer from another platform.
The question on SO is still unanswered. Therefore, I am asking it here, how should I behave in this scenario? What can I or what can we do so that the answer from another platform gets documented to the same question on SO?
